SEAL-PRESS.

SPECIFICATION forming part of Letters Patent N 0. 487,346, dated December 6, 1892.

Application filed May 16, 1892- Serial No. 433,141. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL E. CHEESEMAN, a citizen of the United States, residing at Milldale, in the county of Kenton and State of 5 Kentucky, have invented certain new and useful Improvements in Seal-Presses, of which the following is a specification.

Owing to carelessness of operators of sealpresses which einboss or print symbols on Io seals, when such seals are secured to cars or packages the symbol is often made indistinct and sometimes unintelligible.

The object of my invention is to furnish a seal-press which will automatically look a seal in ituntil a clear and distinct impression has been made and not release a seal when. only a partial or indistinct impression has been made on the seal.

My invention consists, primarily, of a mov- 2o able die in a seal-press so constructed and arranged that when a partial impression has been made on the seal the die becomes locked in the seal-press to prevent the withdrawal of the seal,but upon comple ing the impression the die may be withdrawn by the lever, and thus release the seal, all substantially as here inafter described and claimed.

Figure 1 is a side elevation with one side plate partially removed,showing press closed.

Fig. 2 is the same showing the press open.

Fig. 3 is a detail of the hook.

A is a press-head having a lever-arm B rigidly secured thereto.

. O O are side plates secured to the press- 3 5 head by screws or rivets.

D is an end piece having an opening of suitable shape and size to admit the seal to be sealed and embossed or printed. The end piece is secured to the headpiece and side plates.

Within the press-head are mounted two dies E Ea male and corresponding female die, respectively. One of these dies is stationary. The other is adapted to be forced toward the stationary die by lever 13, provided with a cam 1?, bearing against the die E. The die E is provided with an L-shaped recess 6 in the side thereof, and the lever has mounted thereon a hook F by means of pivot f taking thereinto. A tooth f on the hook is adapted to work in the recess, and when a full stroke of the lever B is made itis forced into the tail e of the Lshaped recess by means of a cam-surface b on the lever bearing against a projection f on the hook,-as shown in Fig. 1. hen the lovers are opened, the die E is withdrawn from the stationary die E until the hook is thrown out of the tail of the L-shaped recess by cam-surface b on lever B, as shown in Fig. 2. The book is 6c held in its locked or unlocked position by friction.

It is obvious that while the lever B can force the die E toward the die E it cannot withdraw it until it has. firmly forced die E 6 against die E and the hook engaged the tail of the recessin die E. If a full stroke of the levers has not-been made before they are opened, the hook will move freely in the body of the recess without doing work and the die cannot be withdrawn, but will be held locked by friction-spring G at any point to which it has been forced by the lever B. When the dies have made a partial impression, the operator cannot withdraw the seal until a complete impression has been made.

I have shown one form of construction; but it is evident that the same result may be accomplished in several. different ways.

I claim 1. The combination, in a seal-press, of a movable die, an aotuating-lever, and a diewithdrawing device adapted to automatically engage the die at the limit of its impression movement, substantially as and for the purpose described.

2. The combination, in a seal-press, of a movable die and an actuating-lever having thereon a hook adapted to automatically engage the die at the limit of its impression o movement and to automatically release the same at the limit of its outward movement, substantially as and for the purpose described.

3. The combination, in a seal-press, of a 9: movable die, a cam-lever whereby the die is forced against the seal, and a hook on the lever adapted to automatically engage the die at the limit of its impression movement and withdraw the die,substantially as and for the [co purpose described.

4. The combination, in a seatpress, of a press-head A, levers B B, fixed die E, movable die E, having an L-sba-ped recess therein, hook F, and cams Z? b on lever B, substantially as and for the purpose described.

5. The combination, in a seal-press, of a press-head A, levers B B, fixed die E, movable die E, having an L-shaped recess e therein, book F, cams b b b" on lever B, and friction-spring G, substantially as and for the purpose described.
